Description

Technical Field

[0001] The utility model relates to the technical field of chemical production equipment, in particular to a tower top gas phase condensation device. Background Art

[0002] The top condenser is a device installed at the top of the cooling tower for condensing water circulation. During the operation of the cooling tower, a large amount of heat will be generated due to the evaporation, condensation and vaporization of water. If this part of the heat is not dissipated in time, the water temperature may be too high, causing equipment damage or casualties.

[0003] Existing tower top gas phase condensation devices generally use heat exchangers. The gas phase enters the heat exchanger and is then heat exchanged by the cold medium. However, due to production fluctuations, insufficient heat exchange often occurs. After the cold medium has exchanged heat, it must be cooled by other methods, resulting in a problem of high energy consumption.

[0004] Therefore, it is necessary to invent a new type of tower top gas phase condensation device, which can achieve the effect of heat exchange and waste heat recovery by changing the internal structure of the heat exchanger. Utility Model Content

[0020] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0023] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0024] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0025] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0026] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0027] The utility model provides a technical solution: a tower top gas phase condensation device, such as Figure 1 As shown, it includes a large-volume steam generator 4, a steam outlet is arranged at the upper end of one side of the steam generator 4, the steam outlet is connected to the steam pipeline 3 through a flange, and the steam pipeline 3 is provided with an outlet valve 8; a gas phase inlet is arranged at the upper end of the other side of the steam generator 4, and the gas phase inlet is connected to the gas phase pipeline 1 through a flange; a liquid phase outlet is arranged at the lower end of one side of the steam generator 4, and the liquid phase inlet is connected to the gas phase condensate pipeline 2 through a flange; two liquid replenishing ports are arranged at the lower end of the other side of the steam generator 4, the two liquid replenishing ports are respectively connected to the liquid replenishing pipeline 5 through flanges, a regulating valve 7 is arranged on the liquid replenishing pipeline 5, a liquid level meter 6 is arranged on the steam generator 4, and the liquid level meter 6 is connected to the regulating valve 7.

[0028] Implementation method: first, a certain level of steam condensate or desalted water is added to the steam generator 4 through the replenishment pipeline 5. The reaction tower heats the material through the reboiler to vaporize and rise to the top of the tower to form a gas phase. The gas phase at the top of the tower enters the steam generator 4 through the gas phase pipeline 1 for cooling and liquefaction. The liquid phase returns to the reflux tank through the gas phase condensate pipeline. The liquid phase in the reflux tank is circulated to the tower through the reflux pump. The low-pressure deoxygenated water in the steam generator 4 absorbs the heat of the gas phase and vaporizes to generate steam, which is sent to other users through the steam pipeline 3. The vaporized liquid level of the deoxygenated water in the steam generator 4 decreases. The liquid level meter 6 detects that the liquid level has decreased and increases the opening of the control valve 2. Water is replenished into the steam generator 4 through the replenishment pipeline 5 to keep its liquid level stable and run continuously.

[0029] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
